A beginner's question on thread

[Timothy Wu]

I'm writing a small utility that listens for socket connections, and 
also repond to user inputs via a text menu selection.

In order to respond to both the user and the incoming connections I 
figure I need to use thread.

I think I would use the main thread to handle the menu and spawn a 
thread which listens on a socket.

Now my question is, how do I terminate the server thread if user wants 
to exit the application? If the server just sit there and listen the 
thread would never terminate by itself. What kind of inter-thread 
communications are available and where would I find info/tutorial on that?
